I particularly liked this low-impact relaxation exercise at lunchtime in the office. It really complements my regular high-impact exercise outside of the office twice a week. I think Sarah is a great tutor and I should like to continue. Now that the course is over, I am missing it. I thought the classes were amazing and even at the end of my first class, I noticed my posture had changed at my work desk and I also find that I am now much more conscious of my posture when I am walking. After the second class, I had another revelation in terms of exercising muscles in my body, by relaxing the rest of my body. Overall I found it remarkably subtle and effective. Nothing negative to say about it at all.
